- "'TANk AAND SUPPORTI -Be `it known that I, ALBERT K.. MNs- FIELD, a citizen of the United States, residing at Batavia, county of Kane, State of Illinois, 3 `have invented a` certain new and-useful Im- -provement in Tanks and Supporting Struc-fg` tures Therefor; and I declare the followingl and exact description of' the invention, such as willv enable others skilled inthe art to which it pertains to make and` use the same, reference being had to thev l ,accompanying drawings, which form a part of vthis specification.v i

My invention relates in general to elevated tanks, and more articularly to aksupporting .structure forlsuc tanks. l

The load imposedupon vthefupright col-` umns of a tank-supporting structure is greatv ont tankand structure, land is gradually less.` higher portions of the.

A n object'of est at their base, owing to the weight of the' supporting structure and'to action of wind upon4 the relatively columns.-

sess gradually-increasing strength toward their base corresponding to the gradually-in` creasedload imposed upon them.

y A further object of my invention is` topro-v i *vide a supporting structure .for tanks in which the wooden beams or joist heretofore used in such'structuresbeneath the bottom;

of thetankwill be unnecessary, the bottom ofjthev tank beingsupported directlyupon a series of I-beams counterbalancedby overhanging vthe underlying beams.

' A'still further object of my invention is to provide., a supporting structure for elevated tanks' which will be simple in construction, y.inexpensive in manufacture, and durable in USG.

l the successive sections of the columns united bythe tie-rods being of graduated heights, horizontal girths a pair of parallel ends ofthe columns, and a pluralityy of par- Specicationof Letters Patent. I @puatron sied May 5, 1906. semi No. 315.298.

My invention will be more fully described hereinafter with reference to the accompanying drawings, inwhich the same is illustrated as embodied in a convenient and practicall Figure 1 is an elevational view; Fig. 2, an

f Thesame referencecharacters are 'usedto vdesignate the same p arts in the several figures lof the drawings. y

Reference character A indicates 'a tank of any suitable construction supported in an l v j elevated position by my improved structure. my invention is to provide, a' L tank-supporting structure so arranged that: the columns thereof maybe of the same cross-Q l section throughout their height, and yet pos'-l Referenc'e characters B B2, B, and B? indicate upright columns, preferably formed ofangle-steel, n Each column is composed of twol angle-bars arranged with their apicestogether and rigidly b t", vconnected to the adjacent flanges of the or rivets. n l

. The lower ends of the columns rest upon s suitable foundations,(indicated at B.) The Icolumns preferably converge upwardlyl and are rigidly united together by diagonal tierods and horizontal. girths.I Each column -is united to the adjacent ycolumn by series of diagonal .tie

Rivets or bolts pass through the registering `holes inthe flanges of the columns and bifurcated ends ofthe rods. n The panels of the structure formed by the sections of the columns united by the successive seriesof diagonalA tie-rods are of graduated heights, the panels nearer the supporting-surface being of less height than the veniently constructed, as 4shown in Figs 3 Patented Dec. 25,1906.

the bottom of thetank will be uniformly supi uniform cross-section, of means connecting and H4.

-long column of and 4, in which dandd2 designate angle-bars rigidly united by plates d d. The girths are located within the inner angles-of the columns and' are rigidly united to the anges of the columns by rivets or bolts.

A pair of I-beams F/ land E2 are supported upon the upper ends of the columns and in y of parallel smaller I-beams F are of graduas shown in Fig. 6, in order 'to -beams F. The ated lengths,

directly support the bottom A/ of the tank A.

The I-beams F are arranged so close together that the weight imposed upon the bottom of the tank will be uniformly distributed and sustained without interposing wooden beams beneath the bottom of the tank. The I-beams E, as well as a number of the I-beams F, extend beyond or overhang their supports, so that that portion of the weight supported by the overhang counterbalances in part that portion sustained between the supports. By this construction Ithe weight moment acting on the I-beams is so reduced that the beams may be comparatively light, thereby producing economical construction.

H indicates a platform surrounding the tank and supported upon beams H', H2, H3,

Such beams rest upon short I- beams projecting outwardly from and supported by the I-beams F. G indicates the I-beams for supporting the beam H. The I-beams G overlie a beam e, supported at its ends between the I-beams E and E2 and extend beneath the I-beam f. The short -beams G3 are support ed in a similar manner by overlying the beam e2, which is supported at its ends between the I-beams E and E2 and extend beneath the I-beamf 2.

The I-beams G2 and G4 are supported beneath the ends of the I-beams F F2 in any suitable manner-as, for instance, by the means shown in Figs. 8 and 9,'in which `hangers K pass through holes in the supporting I-beams and after straddling the short .I-beams pass through holes in a keeperplate k, beneath which nuts are secured on the ends of the hangers.

7L indicates-a railing surrounding the platform H.

By dividing the structure into panels of gradually-increasing height, each panel being provided with diagonal tie-rods connecting the portions of the columns in such panels, the strength of the structure is gradually increased toward its base, because a short column will sustain a greater load than a the same sectional dimensions. It is thereby rendered economically possible to -use columns of uniform cross-section and at the same time having the increased strength near their base necessary to support the increased load imposed on them. It will be evident that by my improvement portedj thloughout its area without the use of. supporting wooden beams.

From theforegoing description it will be observed' that I have invented' an improved supporting structure for tanks, which, though simple and inexpensive in construction, is strong and durable.A

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is`

In a supporting structure for tanks, the combination with a plurality of columns, of means for rigidly connecting said columns, a pair of I-beams mounted upon the upper ends of said columns, and a plurality of I-beams supported upon said pair of I-beams and arranged sufliciently near together to afford a support upon which the bottom of the tank may directly rest.
